7 Open APIs, Open Standards, Open Source and Client value: Unified, open, interoperable SDN platform to create an ecosystem of automated network services Client value: Interoperability, agility, and flexibility through a common cloud computing stack Client value: Enterprisegrade, cost effective, open virtualization alternative Client value: Provide cloud users freedom of choice, flexibility, and openness as they have with traditional IT! IBM is a platinum member and active contributor! Contributing DOVE & other technologies! 250+ IBMers working on OpenStack! 10% of Open Stack projects led by IBMers! IBM founding and governing Board member! OVA moving into Linux Foundation to target broader industry visibility! 400+ organizations participate! IBM founding sponsor

8 Benefits & Challenges: End Users Benefit: Open Source Freedom of choice with no vendor lock-in Ability to build your own services and extensions Power to influence direction Typically less buggy and more secure (no backdoors!) Benefit: Community-backed Project Large vendor community enough said Large user base fluid experience sharing Large developer base easier to find skills Build your own : Free (?) Commercial: Powered by ODP

9 IBM SDN-VE Product Suite Connec&vity Service Chaining & UX IBM SDN-VE Platform: Unified SDN controller based on OpenDaylight 2. Connectivity Service Chaining & UX: A service chaining framework that eases deployment of application patterns over the networking tier in data centers. 3. Network Services: Routing, OpenFlow, Security and LB services running on the controller 4. Network Drivers: Plug-ins or drivers specific to network technologies Gateways Overlay Control Servers 5 Security & LB Appliances 5. Virtual Appliances: Virtual-Physical Gateways; Overlay control servers for end-point mgmt; Security & LB Virtual Appliances that are distributed for scalability Data Plane: Virtual switches for data forwarding/ routing, as well as agents for HW elements to enable forwarding control via the SDN controller.

12 Network Virtualization with Open DOVE DOVE (Distributed Overlay Virtual Ethernet) is an overlay based network virtualization service that uses VXLAN for the data plane, and OVSDB for interfaces to the physical network. DOVE has 5 main components - DMC: The DOVE Management Console enable configuration and management of tenants and logical networks and is service running on the controller. Contributed DOVE to #OpenDaylight and working with community DOVE DMC Connectivity Service Northbound UX DCS: The DOVE Connectivity Server is a scale out cluster of virtual appliances that provide address dissemination and management of tunnel end points DOVE Driver Base SDN Platform DOVE Gateways: Gateways are either physical HW switches or virtual appliances that enable physical networks/end points to participate in logical networks, or allow for access to the internet. Gateways Gateways DCS DCS Security & LB Security & LB Appliances Appliances There is ecosystem support for 3 rd party security and LB virtual or physical appliances. Virtual Switches Virtual Switches HW Switch/Appliance Agents Agents Virtual Switches: These are the data plane forwarding elements that create and terminate tunnel end points and provide the overlay data functionality. They are implemented as part of a hypervisor vswitch.

13 Suite of OpenFlow Services Connectivity Service Northbound UX Virtual Switches OpenFlow Services Suite OpenFlow Driver Base SDN Platform HW Switch Agents The OpenFlow apps will work with any industry-standard OpenFlow implementation on virtual or physical switches. Flow Rep. Span and Tap: To efficiently tap and mirror traffic from points within the network for debugging and troubleshooting large scale networks. SPARTA: A scalable per destination multi path service for deployment in L2 Clos topologies that doesn't require new tunnel support in HW. Load Balancer: A datacenter wide layer 4 stateless load balancer which works at line rate along with traffic steering capabilities for scaling software appliances such as security, compliance etc. [not in product yet, contributed to ODP] Logical Networks: Visually define and deploy multi-tenant virtual networks on an OpenFlow fabric Static Flow Pusher: Programming APIs for deploying userdefined OpenFlow rules Policy Manager: unified policy framework for managing security rules, ACL, QoS, and service chain policies OpenStack Neutron: Plug-in for integration with OpenStack Networking using standard Neutron APIs including extensions for L3 and security groups. Service Chaining: basic service chaining to support application patterns on OpenFlow networks Contributed some OpenFlow services; Worked with community on others at #OpenDaylight

14 Benefits & Challenges: Vendor Challenge: Productization User Experience (UX): Deployment Usage Verticals Test: Interoperability, Scale, Availability Sync: synchronization issues with upstream code Benefit: Community-backed Project Large user base fluid experience sharing Large developer base easier to find skills, solutions Benefit: Raises the bar Large vendor community competitiveness Agile developer community internal process agility Pushes innovation via community Improves organizational culture Benefit: Better Focus Focus on customer-driven value Flexible architecture retains corporate value
